Product Description

 It is a high-tech self-adhesive waterproofing membrane made without base material. The surface is covered with polyethylene film, aluminum foil or fine sand. With great elasticity, it can be self-healed in case it is punctured by sand or a sharp object. Great lap joint between two patches of membrane demonstrate its remarkable co-fusion and great elongation. With great bonding force, it won’t crack or come off the substrate to guarantee its waterproofing performance. The membrane with aluminum coating has great insulation when exposed to the sun, which offers normal temperature to the base. It is also specially designed for a sloping roof with hanging tiles and is suitable for roof made with tiles fixed by nails. The waterproofing layer is also watertight even after being punctured. The product has a good self-adhesive and bending properties.

* Sealing parapets, valley gutters

* Sealing capping bolts & roof ridges

* Roof repair of portable buildings



* High elongation, good flexibility, strong viscosity, high fatigue resistance, resistance to puncture.
* Construction is convenient and quick without the involvement of fire. Membranes can be arbitrarily cut as needed.
*4 layers of protection and superior temperature resistance from -20℃ to +100℃ .

* Wide range of use. The products can be widely used in building engineering, joints sealing, corrosive part of pipeline, sealing work and storage sealing, etc.

*Long-lasting protection for at least 15 years



The application temperature should be between 5°C to 45°C. The installation procedures are as follows:

* Unroll only the required length and cut the pieces to the desired shapes and size.

*  Place the pieces of membrane on the area to be covered and check whether they match the profile of the marked substrate.

* Peel off the release film and carefully place the membrane so as to ensure a minimum of 50mm overlapping and then smoothen the membrane from the centre to the edges in order to dive out entrapped air.
